Hello!

The answer is:

The range or output for the given domain is:

(84,24,4,15.25,84)

Why?

To find the range (output) for the given domain (inputs) we need to evaluate the given function with the given inputs or "x" values.

So, evaluating, we have:

- Range with "x" equal to -4:

$f(x)=5x^{2} +4\\\\f(-4)=5*(-4)^{2} +4=5*16+4=84$

- Range with "x" equal to -2:

$f(x)=5x^{2} +4\\\\f(-2)=5*(-2)^{2} +4=4*5+4=24$

- Range with "x" equal to 0:

$f(x)=5x^{2} +4\\\\f(-2)=5*(0)^{2} +4=0+4=4$

- Range with "x" equal to 1.5:

$f(x)=5x^{2} +4\\\\f(-2)=5*(1.5)^{2} +4=11.25+4=15.25$

- Range with "x" equal to 4:

$f(x)=5x^{2} +4\\\\f(-2)=5*(4)^{2} +4=80+4=84$

Hence, the range or output for the given domain is:

(84,24,4,15.25,84)

Have a nice day!

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
